Uninstalls any game data stored for this GameFeaturePlugin and terminates the GameFeaturePlugin. If the given PluginURL is not found this will create a GameFeaturePlugin first and attempt to run it through the uninstall flow. This allows for the uninstalling of data that was installed on previous runs of the application where we haven't yet requested the GameFeaturePlugin that we would like to uninstall data for on this run.
